Precisely.... without the 'preempt', the first router (RSM, MSFC, etc) would never take control back from #2 after coming back up....
I would also be suspect of all of the lines that say 'standbye'........ hehe =) Seriously tho, just for overkill, we always put preempt on all HSRP groups...... it won't allow a lower priority router to take over, but keeps things in order (if there are more than 2 involved).... BTW, why are you tracking VLANs? Not to say that it's not possible or needed, but I've not seen that..... Mike W.
